Oral B® as well as Water Pik® are oral douches for removing leftovers and plaque from interdental gaps with the aid of a dental water jet. Please be aware that this instrument does not replace the toothbrush, it's rather a additional option for good oral hygiene. A toothbrush cleans the areas above the gums, whereas the water pick destroys plaque underneath the gums as well, in the so-called sulcus. Oral rinse only works if plaque is soft. Only soft plaque can be removed with a water jet. Tough plaque can be eliminated with dental floss and/or during professional dental hygiene. In the video you can see the correct application of an oral water jet and it's advantages for your oral health.
